If this is possible, ie thru Plex API or tautali, I would give it a +1

I Often find myself downloading multiple copies and not always just getting a better quality copy.

Another thing that I've been thinking is that I see a lot of movies posted that are also already on Netflix or Amazon. The IMDb tab has an option to bookmark on Amazon (Amazon owns IMDb) however I cannot login to IMDb because my IMDb account is tied to my Google account and Google has apparently blocked the app.
If there was a way to show an indicator that a movie was on Netflix or Amazon that would be great
